This Retsch Sand Mill Mixer Blender is a used blender and mixer — sometimes referred to as an attritor mill or stirred media mill — designed for fine grinding and mixing of materials in liquid suspension. Retsch is a well-established German manufacturer known for producing laboratory and industrial size-reduction and sample-preparation equipment, serving industries such as pharmaceuticals, chemicals, food processing, and materials science.
The machine is constructed from a combination of mild steel and stainless steel and offers a working capacity of 20 litres. Power is supplied by a 17.5 kW motor rated at 380 volts, and a variable speed drive is fitted, allowing the operator to adjust rotor speed to suit the material being processed. The attritor mechanism is present and confirmed.
The grinding chamber housing measures 230 mm in diameter by 485 mm in length, with both the inlet and outlet sized at 25 mm in diameter. A mechanical seal is installed to prevent leakage around the rotor shaft. The vessel is jacketed for temperature control, and the rotor itself is also jacketed, enabling precise thermal management during processing — a feature particularly valuable when working with heat-sensitive materials. The machine is supplied without grinding balls.
The unit's footprint measures 1.3 by 0.75 metres, and the total installed height is 1.75 metres. The machine is located in Barneveld, Netherlands. The manufacturer's plate is missing, so the production year is unknown. Condition is used.
